The sansevieria genus has tons of different succulents. Today we will consider sansevieria ehrenbergii. Sometimes called blue sansevieria or sword sanseveria, it has long, blade-like leaves. A dwarf cultivar also exists, popularized as the dwarf samurai.
The shape of this plant is unusual, with layers of leaves stacked on top of each other. It makes a beautiful centerpiece of a succulent garden. But do not forget that it can also be grown indoors. This air-purifying plant is also a dazzling houseplant!
So let’s dive deep into the world of the sansevieria sword and discover everything that this beautiful plant has to offer!
All About Sword Sansevieria
The fan-shaped shape of this succulent is magnificent. The long leaves bend slightly as they extend outward from the plant. A groove is formed along the inner side of the leaf that can capture water and direct it to the center of the plant.
Leaf development begins in the center of the plant. Each leaf forms above the one below, but goes in the opposite direction. This layering effect is quite beautiful, creating a zigzag pattern along the stem.
Normal-sized blue sansevierias can have leaves up to 5 feet long. These leaves are often aged and rotted to produce fibers used to make twine or fabric.
A dwarf cultivar called Samurai has much shorter leaves, but forms the same layers. This stocky variety comes in a pure green or variegated coloring of the leaves. Another variant, Banana, has a distinctive banana shape for its new leaf growth.
These plants also produce flowers! Although rare, sansevieria ehrenbergii produces grayish-white or gray-green flowers. From time to time they also take on a purplish tint.
A plant native to Africa, it grows naturally from southern Libya to Tanzania. One of its common names, oldupai, is a direct reference to the Olduvai Gorge in northern Tanzania.
Care Sansevieria Ehrenbergii
Generally low-maintenance, these plants can survive despite careless conditions. Nevertheless, for the most symmetrical and awesome plants, there are goals to be achieved. The ideal growing conditions for creating vigorous and healthy plants are detailed below.
Light and Temperature
Full sun is ideal for growing your sansevieria ehrenburgii. Sword sansevieria is a sun-loving plant! But if you grow it indoors, provide as much light as possible. Opt for your sunniest windows and make sure that there is at least 6 to 8 hours of sunlight a day.
Temperatures below 50 degrees can start to cause cold damage to your plant. Although it can survive up to a slight frost, you will notice damage to the leaf blade. Soft spots, sunken parts of the blade or browning of the edges may occur. His preferred temperature is between 60 and 85 degrees.
Temperature and humidity
Like most succulents, the blue sansevieria stores water in its leaves. It is better to water deeply, but rarely.
Potted plants, such as dwarf samurai or younger plants, must be watered in a specific way. When the soil has become dry, water deeply until excess moisture drains from the pot. Let it drain off the excess, then do another shallow watering and leave it. Do not water again until the soil is dry again.
For Earth plants, this is a similar method, but check the soil at least a few centimeters lower. Water once it has dried, but deeply, soaking the soil at least 6″ below the surface.
During the winter months, you can significantly reduce your watering. Do not let your plant sit in soggy soil or pool water, as it can develop root rot.
Your plant likes a little more moisture in hot weather. Place your pot on a pebble tray with water to increase the humidity of the air around your plant. Outdoor plants would benefit from a light misting early in the morning to increase the humidity.
A porous and well-draining potting soil is ideal for your sword sansevieria. Opt for a mixture optimized for succulents whenever possible. These gritty mixtures quickly drain excess moisture and are robust enough to support the plant.
If you do not have access to a commercial mixture, use a mixture of equal parts sphagnum peat moss, perlite and coarse sand.
During the active growing season in spring and summer, fertilize monthly. Use a succulent liquid fertilizer, diluted by half. Replace one of your waterings with the fertilization session.
Usually you can reduce the frequency in the matter. Avoid fertilization during the winter months.
Repotting is infrequent, as the blue sansevieria grows slowly. There are two times to repot: when it becomes rooted and when it tilts the pot.
As the largest sansavierias swords develop their long leaves, they can become heavy. Be sure to opt for a wide pot that can support the long blades of the plant. The dwarf samurai sansavieria is often much easier and rarely needs to be repotted.
When there are too many roots in the pot, it’s time to divide your plants. Let’s talk about this in more detail.
There are several ways to propagate this plant species. Sanseviera ehrenbergii occasionally forms lags that can be replanted. But it can also be propagated by division or leaf cuts.
Like most plants with rhizomatic roots, the division of the roots is relatively simple. Remove your plant from its pot or carefully loosen the soil around it in the bed until you can lift it freely. Dust off excess soil from the roots. Separate the plant into clumps, each with its own fan of leaves and tangle of roots. Plant each root ball separately.
From leaf cuts, treat as you would most succulent cuts. Select a healthy leaf tip and use a pair of sterile shears to cut it cleanly. Let the cut end flake off, which may take a few days. This drying process helps to prevent the cutting from rotting in the ground. Place in a succulent potting soil, about an inch deep, and keep the soil barely moist until it takes root.
You will not often experience pest-related problems with Sansevieria ehrenbergii. In rare matters, you may have a few mealybugs or a spider mite infestation.
For flour scale insects, a cotton swab dipped in rubbing alcohol can be used to remove them from your plant.
Insecticidal soap is usually suitable for spider mite strikes. Before applying it, first test a sheet to make sure that it does not react negatively. If so, opt for a different brand. Most pyrethrin-free insecticidal soaps work well.
The ailments of sansevieria ehrenbergii are relatively not-known. At worst, you may experience fungal root rot due to excessive watering.
